CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 483,872, dated October4, 1892.

Application filed May 13, 1892- Serial No. 432,896. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM O. BUNDLE, of De Smet,in the county ofKingsbury and State of South Dakota, have invented certain new anduseful Improvements in Corn-Planters; and I do hereby declare thefollowing to be a full, clear, and exact description of the in- Vention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to an improvement in corn-planters; and it consistsin the novel features of construction and in the combination andarrangement of parts, which will be fully described hereinafter, andmore particularly referred to in the claims.

My invention is more particularly directed to providing an improved seeddropping mechanism which is most simple in operation, and having fewparts is not liable to get out of order.

Referring to the accompanying drawings, Figure l is a perspective viewof my improved planter. Fig. 2 is a rear plan view of the same. Fig. 3is a detached View of the drive-chain. I

A represents the axle, and B the drivewheels mounted thereon. One of thewheels is made rigid with the axle, and therefore turns therewith, whilethe other revolves by means of the ratchet mechanism 0, whereby themachine may be turned around without operating the seed-droppingmechanism, as will be readily understood.

Mounted on the axle and projecting forward therefrom are the frame-armsD, which are connected at their forward ends by the cross-piece E, andsecured to the under sides of these arms are the furrow-openers F. Tothe rear of the said cross-piece is mounted the table G. Projectingforward from the axle, between the arms D, is the arm H, and mountedthereon is the standard I, and fulcrumed in the upper end of thisstandard is A the lever J, which is connected at its outer tached itwill be seen that the depth which the furrow-openers enter the ground isthus regulated. The rear end of the lever may be depressed to aconsiderable extent and secured in this position by the hook K,projecting from the rear cross-piece A, and by holding the frame thusraised above the pole the furrow-openers will be held above and out ofengagement with the ground, and thus it may be transported with easefrom one point to another, where it is desired to employ the machine.

Upon the opposite ends of the table are secured seed-boxes, and beneaththem are the perforated laterally-moving slides L, whichreciprocatebetween guides M. Pivoted at their outer ends to the said slides are thelevers N, which project toward each other, being pivotally connected attheir meetingends, as shown. These levers are fulcrumed to the tableabout midway between their respective outer ends and their connectedinner ends, so that a forward movement of their connected ends willreciprocate the seed-slides. Projecting from the rear edge of the tableis the support 0, and journaled thereto is the sprocket-wheel P. Looselymounted on the axle A is the sprocket-wheel Q, which is made to turntherewith by means of the clutch-gear R, the teeth of the same being sodisposed as to make the engagement positive when the machine is movingforward, but to slip without turning the wheel when the wheel is movingin the reverse direction. A suitable operating-lever S and connectionbetween the same and the clutch-gear is provided for convenientlyoperating the latter from the drivers seat.

S represents a drive-chain, which moves around the sprocket-Wheels P andQ, and arranged at intervals on this chain are the wedge-shapedprojctions or cams T, which extend laterally from the periphery of thesame, and as the chain makes its revolutions these stops strike one ofthelevers N near its point of connection with the adjacent lever, and bythis means the levers are turned upon their pivots and the slidesreciprocated. This operation will be readily understood, as the saidlever N normally projects into the path traveled by the said cams. Aslot G is provided for the passage of the projections T through thetable edge.

In order to hold the slides normally in a position to be operated by thesaid stop, a spring U is provided, which connects with one of the leversN outward from its pivotal point, and thus the inner ends of the leversare held normally inward, where they will be engaged by each stop T asthey are brought thereto by the revolution of the chain. As will beseen, the links of the drive-chain are made approximately U-shaped, theends of each link being twisted around the loop of the next-succeedinglink.

In order to form the stops T, one end of the stop-link is made longerthan the other, and after being twisted in the usual way around the nextadjacent link-loop it is continued forward the length of one link, wherei it is secured to the end of the said adjacent link. The extendedportion forming the stop T is set at an incline, so as to engage thelever N and push itontward, as above described.

I11 order to space the rows properly and make them parallel, I employ anarm V, which is pivoted at its inner end to the rear edge of thecross-piece A',and which is adapted to turn outward from either side ofthe machine, the recessed projecting ends of the arms D forming reststherefor in either position. The outer end of this arm V extends to then ext-adjacent row, or the last one that has been planted, and dependingfrom this end is a weighted chain or cord, which drags in the furrow ofsaid row, and in this manner the machine is run, enabling the operatorto keep it always at the desired distance from the row last planted. Therows are thus kept parallel, with a very exact measurement between them.

Having thus described my invention, I

' claim 1. The combination, with an axle, a frame mounted thereon,sprocket-wheels on the axle and frame, seed-slides on opposite sides ofthe frame, and pivoted levers for operating said slides, of a drivechainon said sprocketwheels formed of U-shaped links, the ends of some ofwhich being extended over the nextadjacent links to form wedge-shapedprojections, forthe purpose substantially as shown and described.

2. The combination, with an axle, drivewheels thereon, a sprocket-wheelbetween the drive-wheels, and a frame pivotally supported on the axle,of a tongue projecting forward from the axle, a standard projectingvertically therefrom, a lever pivoted to said standard and looselyconnected at its forward end to said frame, seed-slides and pivotedlevers for operating them, a. sprocket-wheel journaled to the frame, adrive-chain encircling said sprocket-wheels, and stops on the peripheryof the drive-chain, substantially as shown and described.

3. The combination of an axle, drive-wheels thereon, a sprocket-wheel Q,a frame extending forward from the axle, cross-board G, levers pivotedin line near the rear edge of the said board, seed-slides connected tothe outer ends of the levers, whereby they are moved transversely acrossthe ends of the said board, seed-boxes arranged over the slides,standard 0, sprocket-wheel P, a chain encircling sprockets P and Q, andstops T, projecting from the edge of said chain, substantially as shownand described.

In testimonywhereof I affix my signature in presence of two witnesses.
